To 'all'lw'homc' may concern.'

Beitknown` that I, THOMAS "GJ PLANT, a citizen ofthe United States, residing at Boston, in the county of Suffolk and'State of lllassachusetts have invented an Improvement in Heel-'Brea'sting Machines, ofwhich the following description, 'in connection with the' accoin'panyingdrawings, is a specification, lik'e letters on the 'drawings representing' likep'art's.V A

The invention'tofbe hereinafter described relates 'te' heel vbresil,ng machines, and more particularly to theniean's forsilstaihing Or supperting thebreasting'stp from the machine frame daring the action of the heel bref'asting'Y ineens,A j

The present Vention is a development of that shovn,"de`s"cribed and claimed prior appleaem, serial No. 501,449, ledo 11, 1909; and its aims'and purposes arefto `fprovide the breasting stop, supporting' means with a siniple and ffectiv'e forin 'of lock', so that When'the breastingr stophas Inet the shoe,` the breasting stop' As`uppc'irtingl means may more inte position to support the breasting 'stop and befe'ifectiyelyflocked, all as Willjbe m'or'e fully set 'forth hereinafter in coi'inecti'onwith the accom' ianying drawings which disclose one form of ineans'Tfor carryin'gtlie invention intd'p'ractical effect. 4

In the drawings:'Figuref1` is a vievv in front elevation of' lthe upper portion of a heel breasti'ng machine Lembodyifglthepresent` in'vention',v soi'ne of: theparts 'being' in section or broken'away to mre'clea'rly disclose others; and 'Figi '2 is a deta-ohedfdetail Showing the bre Sting, step sapporcing means 'and itsfasseeatedipafts. The machine fraine for suppertntg"1 the Operating parts may be"o`f usualand desired character, `aiidliereiii is"`repr'esented' as a column `1, Fig. l, having suitable upwardly extending portions 2 and ,brackets @for sustaining and guiding ythe moving' parts. These" features may be` any form and kind suitable tothe pur Oses intended. j The presserfoot 5,' its carrying 'arms"6 7, theV presserfoot 'slile,"tli'e actuating lee'rl 8 and the actuating' rod maybe substantially aspoiiited out inthe prior application hereinbefore mentioned, and such partsneed nofvfurther elucidatidn at this time.v Simila-rly theA knife carrying slide 10, its aotuating' rod 11.,they nieans'for reciprocating the lfnife carryingslide, the knife 'carrier 12( 'and its knife 13 detachably sustained upon the knife carrier by means of the swinging arm 14 to be readily disengaged therefrom, and the footl adjustable in the knife carrier by means of its Vadj usting screW'for limiting the extent of downward movementof the knife, may be as pointed out in'said prior applica` tion, or otherwise, and, as such parts are fully shownjanddescribed in said prior appheation,V- further description and elucidathereof is unnecessary. As pointed out 1n said prior ap'plication,'also, the breast stop Carr-ier 16 is sustained in suitable guides for vertical n'iovement'by means of its actuating lever. 17 pivoted `at 18`and yieldingly operated by the"actuating` rod 19 and its springjQO from a. suitable source of power, and herein maybe substantiallv the same as f`ully v describedv and'shown in the said prior application.

yThe breasting stop l'cairied by the carrier 16 preferably has its `lower edge coneaved 's`o1ne\vliat,`as indicated in Fig. l, to properly coact `with the contour Of the shoe bottofn to prevent injury thereto` and said breasting'stop cairier may have the breasting stop' portion 22, as pointed out in said prior application,tocoact with the foot 4conrefctedtoth4 knife slide, the construction being such that Whenfthe breasting stop is in its:loive'red'positionand the knife proceeds on'its cutting'stroke` the Vparts 15 and '22 will come together and the knife Will be arrested bythe breastingstop before `it has injured the `sole of theshoe, ,The breasting stop c`ar rier'hlG"hasfaninclined Shoulder or surface pfrtiOnQS which is adapted to engage a similarly,iiicliiud`- portion of a carrier sup;- poitrQI under conditions to be hereinafter referred to'.

The carrier support 24 is provided with a slot 25 t'owhich is connected one arm of an actuator pivoted 211:27 and haying an arm 28 to which isconnected a spring` 29j the upperendof Which is attached to an adjusting screw 30, the construction beine; such that the actuator Will normally tend `to more the carrier support 24 to the right, or into coactiiie; relation With the inclined shoulder Q3 on the breasting carrier support is free for such Increment.

Mounted on the arm 26 of the actuator is a roll 31 u"hi`ch` is normally engaged by a cam track 32 `carried bythe knife slide, when the partsare innon-breasting# position, that is,

stop carrier, when said Vpressure upon the scends, comes opposite the roll 31 and per-v to move the carrier sup-- mits the spring 29 port 2li: into carrier supporting position.

The parts thus far described maybe substantially as fully disclosed in the said prior application or they may be modified in form, character' or design to suit the conditions of use. ln said prior application when the carrier support had been. moved into cooperative relation with the stop carrier, a lock was provided to hold the carrier support in its carrier supporting position.

The present invention contemplates as one of its characteristics the provision of means for locking the vcarrier support in its carrier supporting position, such means acting to prevent moveijnent'of the support in either direction, as will be hereinafter more fully described. As one means of carrying this feature of the invention into effect, the supporting frame or bracket 3 is provided with aplate' 34, the surface of which is corrugated or provided with teeth, as indicated in Figs. l and 2. The carrier support 24 is likewise provided on its lower edge portion with a series of teeth 35 which are adapted to coact with the teeth of plate 3e when the carrier support 24 is moved into supporting position. l ln order that the carrier support may be moved to and from its carrier supporting position, the said carrier support is yieldingly sustained with its teeth 35 normally out of engagement with the coacting teeth of the plate 34, and as one means of carrying this feature of the invention into effect a pin 36 is provided which projects through a suitable opening in the frame and bracket 3, the lower end of said pin being sustained by a spring or yielding element 37, secured in appropriate manner, as by a screw 38, to the' machine frame or bracket 3, the construction being such that while the spring 37 supports the pin 36 in its upward projected position to maintain the teeth of the carrier support out of engagement with the teeth of the plate 3-l, yet any downward carrier support 24: will at once depress the supporting pin 36 'and bring the opposed teeth into interlocking engagement.

'From the construction thus described and from the operation of the parts as announced in said prior application, it will be noted that the hreasting stop carrier is caused to be moved downward to bring its lower portion 21 into contact with the sole of a shoe, such action in the presentfo-rm of the invention being effected lever and rod 19 and its yielding spring 20. This movement of the breasting stop carrier brings its shoulder or inclined surface 23 into a. position determined by the thickness through the actuating of the work or the position thereof. Upon depression of the breasting knife carrier and its knife to perform the breasting operation, the cam track 32 moves downward until the roll 31 may move into tlie'recessed portion 33, whereupon the carrier support 2l moves in response to the spring 29 to bring its inclined surface 39 into contact with the shoulderv or inclined surface 23 of thebreasting stop carrier. Owing to the inclined cooperating relation of these two surfaces, movement to the right of the support 24 causes the said support to be forced downward with lsufficient energy to depress the supporting pin 36 against the tension of its sustaining-spring 3 and causing the coacting teeth to interlock. It' will be noted' that this interlocking of `the teeth takes place through the sliding contact of the two inclined surfaces 39 and 23, and the energy of the spring 29 is not sufficient to cause upward movement of the breasting sto-p carrier against its actuating spring 20, therefore alldisplacement ofthe breasting stop carrier and breasting stop,when the parts have once assumed operative position with respect to the work, is avoided. Upon further movement of the breasting knife during its heel breasting operation, the support 24 carried hy the machine frame or other stationary part serves to sustain the breasting stop carrier, with the result that as the foot 15 moving with the breasting knife, contacts with the part 22 of the breasting stop -v carrier, further downward movement of the knife is arrested, and the arresting force is transmitted directly to the machine frame or other stationary part carrying the carrier support 24.

It will be noted that the interlocking teeth effectively preventthe carrier support from movement in either direction after they have become engaged, and that consequently as the support moves into this engaging position the teeth become interlocked before sufficient force is exerted on the support to disturb the correct 'position of the breasting stop carrier, andv therefore, also, movement of the support ,in the reverse direction away from the supporting position isprevented upon the downward thrusting action of the knife. l l i Obviously various forms of yielding means may be devised for sustaining the carrier support 2li with the interlocking teeth in non-interlocking position to permit free movement of said support to and from carrier supporting position, but the simple device herein provided has been found to be a convenient and economical arrangement.
